导航抽屉，TabLayout，ViewPager，汉堡图标应用程序

Question

我正在创建一个带有标签和viewpager的导航抽屉。汉堡包图标未显示在工具栏上，标签标题也未显示。我尝试通过调用viewpager.setCurrentItem（）方法打开导航抽屉中的一个选项卡。在发布此问题时，我的Android支持库是最新的。请查看代码并指出我的错误。

public class MainActivity extends AppCompatActivity {

private DrawerLayout drawerLayout = null;
private NavigationView navigationView = null;
private Toolbar toolbar;
private ActionBarDrawerToggle actionBarDrawerToggle;
private ViewPager viewPager;
private TabLayout tabLayout;
private ViewPagerAdapter viewPagerAdapter;
private int navItemIndex = 0;
private String[] activity_titles;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);  //error occurs here

    getSupportActionBar();
    setSupportActionBar(toolbar);

    toolbar.setTitle("Eat Where");
    initWidgets();
    initNavMenu();
    initTabLayout();
    setUpViewPager();

    activity_titles = getResources().getStringArray(R.array.nav_item_activity_titles);

}

private void setUpViewPager() {
    viewPagerAdapter = new ViewPagerAdapter(getSupportFragmentManager(),tabLayout.getTabCount());
    viewPager.setAdapter(viewPagerAdapter);
    viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
}

private void initTabLayout() {
    tabLayout.addTab(tabLayout.newTab().setText("HOME"));
    tabLayout.addTab(tabLayout.newTab().setText("FAVORITES"));
    tabLayout.addTab(tabLayout.newTab().setText("NEARBY"));
    tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
    tabLayout.setupWithViewPager(viewPager);
}

private void initNavMenu() {

    actionBarDrawerToggle = new ActionBarDrawerToggle(MainActivity.this,drawerLayout,toolbar,R.string.nav_drawer_open,R.string.nav_drawer_close){
        @Override
        public void onDrawerOpened(View drawerView) {
            super.onDrawerOpened(drawerView);
        }

        @Override
        public void onDrawerClosed(View drawerView) {
            super.onDrawerClosed(drawerView);
        }
    };
    drawerLayout.setDrawerListener(actionBarDrawerToggle);
    actionBarDrawerToggle.syncState();


    navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
        @Override
        public boolean onNavigationItemSelected(@NonNull MenuItem item) {

            switch (item.getItemId()){
                case R.id.nav_home:
                    // This line below does not jump to the requested tab
                    viewPager.setCurrentItem(item.getItemId());
                case R.id.nav_favorites:
                    viewPager.setCurrentItem(item.getItemId());
                case R.id.nav_nearBy:
                    viewPager.setCurrentItem(2);
            }
            return false;
        }
    });
}

private void initWidgets() {
    drawerLayout = (DrawerLayout) findViewById(R.id.dLayout);
    navigationView = (NavigationView) findViewById(R.id.navigationView);
    viewPager = (ViewPager) findViewById(R.id.viewPager);
    tabLayout = (TabLayout) findViewById(R.id.tabs);
    toolbar = (Toolbar) findViewById(R.id.toolbar);
}



@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.nav_menu,menu);
    //getMenuInflater().inflate(R.menu.overflow,menu);
    return super.onCreateOptionsMenu(menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {

    int id  = item.getItemId();
    switch (id){
        case R.id.menu_settings:

    }

    if (actionBarDrawerToggle.onOptionsItemSelected(item)){
        return true;
    }
    else
        return super.onOptionsItemSelected(item);
}

}

logcat的错误如下所示：

我知道这是一个很长的问题，但我的项目需要这个。任何帮助将不胜感激。

Answer 1

如果要添加抽屉布局，则必须在xml布局中添加<android.support.v4.widget.DrawerLayout>作为父标记，并在其中保留<android.support.design.widget.NavigationView>。
